Peer-to-Peer Networks: Security Analysis

Executive Summary

In this paper, the authors are dealing with security in highly distributed systems, specifically peer-to-peer networks. They are describing some known theoretical attacks and defenses in these kinds of networks and comparing them with real world data. Classification of attacks realizable in peer-to-peer networks is given. They also discuss influences of their combinations. This could be useful for creating models of peer-to-peer networks' defense and malware spreading. Also they are proposing their new system for automatic downloading and detection of new viruses in peer-to-peer networks, together with all possible extensions.
